Looking for the name of an old toy and educational product I had when I was a kid. It consisted of a small (maybe 12"x12") moniter / viewer that came with plastic slides that were inserted vertically into the top of the veiwer and pushed down. I think you had to plug it in to work. As the moniter displayed the pictures from a plastic slide like a slide projector, the plastic slide would be extruded from the machine one slide at a time. I remember they had a slide about dinosaurs and one on mixing colors of the spectrum. I don't remember how the naration and sound was recorded. I think it was actually by inserting a small 45 type vinal record at the top. Any ideas?

Yes, they were called slide viewers. You bought the viewer and any number of "education" slides. Later models had a small vinyl record (I thought on the bottom) that played. The feed was automatic or could be controlled by a push down switch on the side.

They were definitely a kids' toy, not a viewer for adults to view their slides.

What ideas are you looking for? Where to buy one? What they were called?

Thank you. I was wondering what they were called and who made it.

Found it. They were called Show n tells by GE. Here is a link to Ebay where they are still selling them.
